Abstract

The invention discloses a mold on-line monitoring and protecting method based on shape outline matching. The on-line monitoring and protecting method comprises the following steps that a near infrared mixed visible light illuminant produces near infrared mixed visible light on a mechanical jig; an image obtaining device obtains an image of the mechanical jig and transmits the image to an image processing device; the image processing devices receives the image information of the image obtaining device, an image processing algorithm in shape outline matching is adopted, and the shape outline of collected near infrared merged visible light image of the mechanical jig is matched with the shape outline of a standard image; a control command is generated according to a matched result; a jig control system receives the control command of the image processing device, so that the motion of the mechanical jig is controlled. Through the adoption of the on-line monitoring and protecting method disclosed by the invention, the information whether a movable die and a fixed die are good or not can be quickly and accurately obtained, and the defects of a conventional mold on-line monitoring and protecting technique are overcome.

Description

[0001] This application is a divisional application of the patent with the application number 201410494784.8 and the patent name "Mold Online Monitoring and Protection System and Method Based on Contour Matching". technical field [0002] The invention belongs to the technical field of electronic information, and relates to a mold monitoring system, in particular to an online mold monitoring and protection system based on contour matching; at the same time, the invention also relates to an online mold monitoring and protection method based on contour matching. Background technique [0003] Injection molding machine is the most important molding equipment in the processing industry, and its dynamic and fixed molds are directly related to product quality. In addition, since the movable and fixed molds account for a large proportion in the processing and production costs, their service life directly affects the product cost. Therefore, improving the safety level of dynamic and ...
